The Stanley Quencher is a double-wall vacuum-insulated stainless steel travel tumbler, built from recycled 18/8 stainless steel with a BPA-free, splashproof Flowstate three-position twist-off lid. Its tapered base fits most car cup holders, and the 20 oz size is the compact version of the popular 30 and 40 oz Quenchers. It suits commuters, desk workers and anyone who wants cold drinks through a long day without refilling. Against rivals like the Yeti Rambler and Owala tumbler, the Quencher's draw is the lid's three drinking positions and the cup-holder-friendly base; the trade-off is that the 20 oz holds less than the larger Quenchers many people carry.
